GRAIN-DRILL.

SPECIPICATION formingpart of Letters Patent No. 324,110, dated August 11, 1885.

Application filcd March 14, 1885.

To all whom it may concern:

Be it known that I, ADAM O. HENDRIoKs, a citizen of the United States, and a resident of Shenandoah J unction, in the county of J offerson and State of West Virginia, have invented certain new and useful Improvements in Grain-Drills, of which the following is a description.

The invention relates, particularly, to the mechanism which is employed, in connection with the seed-hopper, for-regulating the flow of grain from the hopper to the drill-boot and for indicating the rate of such flow; and it consists in certain novel features or elements in the construction of such mechanism and in certain novel combinations of su ch features or elements, as will be hereinafter described and 1 claimed.

In the drawings, Figure 1 is an end elevation of the seed-hopper of a grain-drill to which my improved mechanism is applied. Fig. 2 is an elevation of a portion of a seedhopper, which has my improved seed-discharge mechanism applied thereto. Fig. 3 is an elevation showing the interior face of one of the two main exterior sections of the dischargespouts. Fig. 4 is an elevation showing the interior face of the other of the two main exterior sections of the dischargespouts. 5 is a vertical longitudinal central section of the discharge-spout at right angles to the'lin'e w w of Fig. 6, the bearing-shaft being rem oved. Fig. 6 is a plan view of one of the dischargespouts detached from the hopper and from the revoluble supporting-shaft. Fig. 7 is a side elevation of the ring-cap, and Fig. 8 is a side elevation of the shouldered ring.

To the lower'face of the seed-hopper A are securely attached a series of discharge-spouts, A', corresponding in number to the orifices in the bottom of the hopper. The dischargespouts A' are each composed of two distinct outer sections or shells, a and a', an irregular ring or cylinder, D, and a recessed ring-cap, O, the ring and the ring-cap being received within circular openings in the sections or shells a and a', and the spouts, as thus constructed, encircling the revoluble actuating shaft B, the shells being secured together by their perforated lugs a a', bolts af, and nuts Fig. i

(Model.)

c. The recessed ring-cap Ciis of such diametween the ring on the one side and the ringcap and its shell upon the other side a passage, p, through the lower portion of which the seed is carried from the inlet portion to the outlet portion of the spout. In assembling the parts the ring D is placed within the Opening in the shell a from the larger side thereof, and it is then retained in its position by the securing ring or collar df, which is fitted closely upon the cylindrical portion (12, and against the end of the tapering extension a2 of the shell a. The ring D is provided with arms or prongs d, which project from it in a direction parallel with the revoluble actuating shaft B, and are received within oorresponding perforations, c c, formed in the adj ustable ring-cap O. The ring-cap or slidable valve O is provided with a set-screw, G', by which it is adjusted upon the shaft B; and it will'be perceived that the ring and the ring-cap thus locked together and to the revoluble shaft, will all rotate together Within the two fixed shells a and a'. o i

In Operation the seed received through the? To one end of the hopper is Secured a plate,I

G, which is provided upon its outer face with a short journal, g, to receive a cogged indexplate,G',and with a lower annular unthreaded extension, 92, which receives an adj ustingscrew, H, which terminates exteriorly in a squared end, h, upon which is fitted a gearwheel, H',which engages with the index-plate G', the inner end of the screw engaging with a threaded arm, i, of a ring, I, which lis loosely sleeved upon the shaft B, and Secured against longitudinal displacement thereon by ashoul- ICO der, b, and an adjnstable ring-collar, b', or by other suitable means-such as a sliding;` ring and a set-screw npon either face of the ring` I. The annnlar extension o* is perforated and. threaded to receive a sct-screw, g, by which movement of the enlarg'e'd portion h' of the adjnsting-screw H within the extension g is prevented.

The rng-cap or regulating-valve O, being suitably adjusted at the ontset for the discharge of any desired quantity of seed. per acre, and the index-plate G' being iitted by its pointer G to correspont', it is thereafter necessary only to change the adjnstment of the gear-wheel H' actuating; the screw if in order to alter the rate of discharge through all the spouts of the series, and at the same time and by the same movement to change the position of the pointer npon the indexplate so as to indicate the change in the rate of discharge. The adjust-nient of the screw H, actuating the ring I, the shaft, and its series of ring-caps or valvcs, may be eft'ected by manipulation of the index-plate, or by means of a winch applicd to the squared end bl of the screw H.

It will be understood that the shaft I is made revolnble, as the vehiclc advances, by any suitable gearing which connects it with the axle-tree of the machine.

I am aware that mechanism has before been provided in connection with a grain-drill in which a series of disks are scenred npon a longitndinally-movable feed-shaft, so as to be adjustable toward or from a correspondiug series of spouts or cases, which are secured to the bot-tom of the feed-hopper; and j am also aware that it is not new to provide, in connection with the diseharge mechanism of the character described, means for indicatingI the rate at which the grain is beingr discharged, and for varying` such rate by adjnstin` the feed-shaft, as before stated. do not therefore broadly claim cither regulating-valves npon a feed-shaft and oru-,rating in connection with dischargesponts, or mechanism for impartingmotion to a Iced-shaft and its valves, or for indicating1 the rate of discharge.

az-tllo Having' described my invention, I claim as newl. The combination, in a grain-drill, of a secd-hopper, a discharge-spout which is provided with a circular perforation attached to the bottom. of the seed-hopper, a ring which is provided with arms or prongs within the circular perforation, and an adjustable ringcap or rt'gnlating-valve which is provided with perforations which correspond to and are engaged by the arms orprongs upon the rinfj. 2, The combination, in a grain-drill, of a revoluble shaft, and a discharge-spont which is composed of two vertically-arranged sections which are placed face to face, as described, one of the sections having combined with it a central horizontal ring or cylinder which is provided with n'Qectingarms which extend through the opposite side ot' the discharge-spout, and the other section having within its central horizontal Opening a regulating-valve which is provided with perforations which are engaged by the arnis npon the horizontal ring, substantially as set forth.

i. The combination, in a grain-drill, of a rerolnble shaft, a dischargc-spout which is composed of two vertically-arranged central- .ly-perforated sections which encircle the revoluble shaft and are placed face to face, as described,one of the sectionshaving combiued with it a central horizontal riug or cylinder which is provided with arms which extend through the Opening in the other section and project beyond the same, and the other seetion having` within its central horizontal opening a reguIatiug-valve which is provided with perforations which are engaged by the arms upon the horizontal ring, and mechanism, as set forth, for indicatine` the rate at which the contents of the feed-hopper are being discharged.
